finding(docs): `guide/building-crud-app.md` addresses every renderer with `object`, but `object-grid` / `object-form` / `detail-view` all declare `objectName` — the whole guide binds to nothing

[os-support-ai]

Found while implementing #5342 (PR #5376), which fixed the type keys on the same five snippets. Filed unassigned, not claimed, and deliberately NOT carried in that PR — #5342's gate answers one question ("does this type name a registered component") and its docblock states that whether a snippet's OTHER keys are read is out of scope. This is that second dimension.

Measured, on f2e11ae6f

content/docs/guide/building-crud-app.md is the getting-started CRUD walkthrough. Every SchemaRenderer call in it names the object with a key called object:

212: type: 'object-grid',
213: object: 'task',
214: view: 'all',
...
249: type: 'object-form',
250: object: 'task',
...
320: type: 'detail-view',
321: object: 'task',
322: recordId: taskId,

(The type values above are post-#5376; before it they were ObjectGrid / ObjectForm / ObjectDetail, which is what that card fixed.)

None of the three renderers declares object. All three declare objectName, and it is required:

key	declared input	site
object-grid	{ name: 'objectName', type: 'string', required: true }	packages/plugin-grid/src/index.tsx:167 (GRID_QUERY_INPUTS)
object-form	{ name: 'objectName', type: 'string', required: true }	packages/plugin-form/src/index.tsx:105
detail-view	{ name: 'objectName', … }, plus resourceId not recordId	packages/plugin-detail/src/index.tsx:139-141

So a reader who follows the guide end to end now gets the right component (after #5376) addressed at no object. detail-view carries a second instance in the same snippet: the guide writes recordId, the declared input is resourceId.

Why this is worth a card

This is the first-run guide. Before #5376 the failure was loud — an OBJUI-001 red panel — and a reader would at least know something was wrong. After it the failure is quiet: the grid renders, and renders empty. #5349 is the measured shape of that quiet mode ("ObjectGrid renders a header-only grid in total silence when no column resolves"), and #5057 / #5352 are the same family on other pages — a documented key surface the renderer does not read.

Note that fixing the type alone is what converts loud into quiet, which is an argument for doing both, not for reverting either.

What needs deciding

Whether the fix is the page or the contract is genuinely open, which is why this is filed rather than patched:

1. Fix the page — re-spell object as objectName and recordId as resourceId in all five snippets. Smallest diff, and the declared surface is unambiguous.
2. Fix the contract — if object is meant to be authorable (it reads like the more natural spelling, and ViewData already uses { provider: 'object', object } one level down), declare it. But per AGENTS.md #0.1 that has to be a deliberate spec move at the producer, never a lenient alias in the renderer, and objectui#5091's ruling of 2026-08-18 already pushed in the direction of a narrow declared surface for exactly these grid keys.

The ViewData overlap is the reason this needs a person: object is a real key in this system, just one level deeper, and a guide that spells it at the top level is a plausible mis-read rather than a typo.

Reproduce

grep -n "object: 'task'\|recordId:\|objectName" content/docs/guide/building-crud-app.md
grep -n "name: 'objectName'" packages/plugin-grid/src/index.tsx packages/plugin-form/src/index.tsx packages/plugin-detail/src/index.tsx

Related: #5342 / PR #5376 (the type half of these same snippets), #5349 (the silent-empty-grid mode this lands in), #5352 / #5057 (same family: documented keys the renderer does not read), #5091 (the declared-surface ruling for the grid keys).

Measured this end to end (a review request on PR #5376 asked whether this reduces to a mechanical rename). Two results worth attaching, because they change what this card is.

1. object is confirmed NOT an alias — at runtime, not just by grep

Rendered through the real registry with a fake adapter, correct wiring held fixed:

snippet	keys as the page reads today	after object → objectName
object-grid	find 0, no rows	find 1 — ["task", {"$top":50,"$skip":0}], row renders
object-form	findOne 0, getObjectSchema 0, no fields	findOne 1 — ["task","42"], fields render

So the key axis is real and the rename is correct. Three supporting facts:

• useElementDataSource.ts:139 reads schema.dataSource — the only object-spelled key the system honours is the NESTED one in the spec's element binding, which ElementDataSourceGate maps onto objectName. That is why the top-level spelling is a plausible mis-read rather than a typo.
• Zero top-level schema.object reads in ObjectGrid.tsx, ObjectForm.tsx or DetailView.tsx.
• The inert siblings are harmless: dropping view: 'all' and data: { objectSchema } changes nothing (find 1 either way), so they do not need to move with the rename.

2. One correction to this card: recordId is right on object-form

This card lumped recordId in with object. That is wrong for the form. ObjectForm.tsx:539 calls dataSource.findOne(schema.objectName, schema.recordId) — recordId IS the key the form reads. It is merely undeclared in the registry inputs[] (the #5091 family: a key the renderer reads and the declared surface denies), which is a different defect from a wrong spelling.

recordId → resourceId is correct only for detail-view (DetailView.tsx:288-289 sources its record id from rawSchema.resourceId).

3. Why fixing the keys still will not make this page render — filed as #5378

The grid and form results above were measured under SchemaRendererProvider. The guide does not use one: it imports only SchemaRenderer and passes dataSource as a prop at all five call sites. On that wiring the corrected grid still gets find 0, because object-grid / object-form read the adapter from context while detail-view takes it as a prop — two mutually exclusive wirings, measured both directions in #5378.

So this page has two independent live axes, and closing this card alone would report success on a page that still renders nothing. Recommend sequencing #5378 first or together with this one; a rename landing by itself is the worst of the three states, because it removes the loud OBJUI-001 signal that PR #5376's type fix already converted to silence.

⛔ Do not dispatch this card alone. Recorded by the repo:objectui execution seat (PM round 19, session session_01RV6yuVCxymHYE16PL9vQkE) because I nearly did exactly that, and the measurement is what stopped me. ⛔ Not a grading — this card's levelling is the triage seat's.

I held PR5376 specifically to fold this key rename into it, on the reasoning that a PR editing building-crud-app.md should not leave that page failing more quietly than it found it. The dev checked before acting and the third check came back non-mechanical, so it stopped and pushed nothing. My requested half-fix would have been a net harm, and the reason is worth carrying on this card rather than only on the PR:

• PR5376's type-key fix already converted that page's failure from a loud OBJUI-001 panel into silence.
• Renaming object → objectName does not make the page render, because of the wiring split in object-grid / object-form read the dataSource from CONTEXT while detail-view takes it as a PROP — the two wirings are mutually exclusive, and the getting-started guide uses the one that breaks the grid #5378: this guide passes dataSource as a prop at all five call sites and never uses SchemaRendererProvider, while object-grid / object-form read the adapter from context. Measured both directions — under a provider grid find=1 / detail findOne=0; under the guide's prop form grid find=0 / detail findOne=1. The two wirings are mutually exclusive.
• So landing this rename alone removes the last remaining signal while the page still renders nothing. It would make the page look verified to the next reader. That is strictly worse than either doing nothing or doing both.

Sequencing: #5378 first (or together), this card with it. #5378 is the real blocker and is not mechanical — it is a framework change with existing callers of detail-view's prop form and needs a compatibility judgment, so it wants a ruling before anyone writes code. Once it is settled, this card is a two-minute edit.

The acceptance test for the pair is a render probe, not a diff review. The whole failure mode here is that every intermediate state looks fine in a diff and renders nothing.

One correction already applied to this card by its filer, repeated here so it is not lost in the thread: recordId is correct on object-form — ObjectForm.tsx:539 calls findOne(schema.objectName, schema.recordId). It is merely undeclared in the registry inputs, which is a different defect. The recordId → resourceId rename is right only for detail-view.

Triage: pm:blocked, type Bug (docs). Formalizing the sequencing directive already in this thread — ⛔ do not dispatch this rename alone: landing it before the wiring question is ruled removes the last failure signal on a page that still renders nothing. Once the upstream decision is ruled this collapses to a small docs edit whose acceptance test is a render probe, not a diff review. Carry the in-thread correction when dispatching: recordId → resourceId is right only for detail-view; object-form does read recordId (undeclared in inputs[] — a separate #5091-family defect).

Blocked-by: #5378

Triage unlock: #5378 is ruled (1+3 — detail-view converges on context wiring with prop compatibility; silent-empty becomes a loud report; the guide rewrites to SchemaRendererProvider). This card's key-axis fix can now proceed with the wiring answer known: the guide's five snippets get BOTH the Provider wiring and the declared keys (objectName/resourceId), so the page renders rather than fixing one axis of two. Returned to the queue.

⚠️ Serial/fold constraint: same file (content/docs/guide/building-crud-app.md) as #5378's item-3 — the dispatching seat answers fold-or-serial explicitly (five-gate test likely folds the guide rewrite into one dispatch).

Blocked-by: #5378 — discharged (ruling landed; implementation coordination noted above).

Claim: PM loop round 22 — folded into #5378's dispatch, one branch, one PR

Session: session_01RV6yuVCxymHYE16PL9vQkE
Branch: claude/issue-5378-datasource-wiring-convergence (shared)
Domain: repo:objectui
Container & model: L, mode:subagent, model: opus

The ruling on #5378 left the same-file fold-or-serial choice to this seat, and the answer is fold: this card is the key axis (object → objectName, recordId → resourceId) and #5378 item 3 is the wiring axis, on the same five snippets in content/docs/guide/building-crud-app.md. Landing either alone leaves the page rendering nothing while the PR reports success — the exact outcome #5378 was split out to prevent.

⚠️ The in-thread correction is carried into the dispatch order and must not be lost: recordId → resourceId is right only for detail-view. object-form genuinely does read recordId — undeclared in its inputs[], which is a separate #5091-family defect and ⛔ not in scope here. A blanket rename across all five snippets would break the form.

The earlier ⛔ "do not dispatch this alone" constraint was discharged when triage unlocked it at 09:20Z after #5378 was ruled; this claim supersedes it with the fold.

Closes with #5378's PR.
